      Hi all.
      I've just found this on the RSGB news website re home networking power line adapters and the interference they cause. A pressure group UKQRM has been set up and they have a petition on line at http://petitions.number10.gov.uk/SaveShortwave2/
      Just for information of our G friends in case they missed it.
      Regards to all
      Lawrence

        Thanks Lawrence,

        The most important thing for any British station, Amateur or SWL, is to make
        their complaint known to Ofcom.

        Below, a copy from a UK amateur on the subject

        The Ofcom telephone helpline doesnt always acheive any result,
        the paperwork seems to get "lost" in the system.

        Better to use the online complaint form.

        The additional information section allows quite a lot of
        information to be added so our PLT complaints can be
        accomodated OK.

        The online complaint results in a telephone reply the
        same or next working day by someone who will have
        dealt with quite a number of similar complaints.

        Best to have a recording made just in case the QRM
        should go off just before Ofcom investigator visits!

        Have had 4 PLTs removed,one replaced by WiFi the
        others by direct wiring which gives a superior connection
        as well as saving power,about 5 watts per PLT unit.

        A fifth unit went out of use by itself,reason unknown.

          Alan,
          I read it on the RSGB news and it is important that everyone responds to put pressure on the authorities, other wise they will not take any action.

          A couple of years ago we saved the 10GHz band in Malta from interference because they were going to allocate TV studio - TX site and OB units to Studio links on it, but we got together and they allocated them above 10.5GHz.

          In the case of Malta it was the 10GHz band, but in the case of the network power line adapters the interference will cause disruption of communications on all the HF bands and beyond. So it is very important for every G station to go and to the website and complain to OFCOM.

          Thanks & regards,
          Lawrence

                Thanks for the pointer - I'm not aware of any manufacturer or importer
                being subjected to the kind of EMC scrutiny as has long been established
                by Deutche PTT e.g. As a matter of fact where UK entities asked for EMC
                specs, we always supplied the document produced by Deutche PTT testers
                who certified our products at source before they were allowed into Germany.
                When I first started using a BBC Micro in its UK plastic livery for
                RTTY, the noise generated was incredible and I had to had to coat the
                inside of the case with aluminium foil and graphite to quieten it to a
                reasonable level + some ferrites on cables.
                My local supplier then opened up a BBC Micro built for the German
                market, it was as if it was made to be bomb proof and many times heavier
                than our specimens.
                Even with PC's in metal cases, I found my Spectrum Analyser module is
                useless for other than connecting directly to a TX output via a switched
                attenuator box.
